What is balloon valvotomy?
Valvotomy is a procedure in which your health care provider
uses a balloon to stretch a heart valve or breaks the
adhesions in a valve that may be scarred. The procedure
can fix some valve problems without the need for surgery.
Heart valves direct the flow of blood through the chambers
of the heart and to the rest of the body.
When is it used?
You may need this procedure if you have a scarred
valve that blocks the flow of blood to the lungs, to other
chambers of the heart, or to the body. This procedure is
not the answer for all people with blocked valves.
Alternatives to this procedure include repairing or
replacing the valve with open-chest surgery. Ask your
health care provider about these choices.
How do I prepare for valvotomy?
Plan for your care and recovery after the operation. Come
to the hospital prepared to stay for a day or two.
Before the procedure tell your health care provider if you
have had any kidney problems or reactions to
iodine-containing foods or chemicals, such as seafood or kidney
contrast dye.
Follow your health care provider's instructions. Do not
eat or drink anything after midnight and the morning before
the procedure. Do not even drink coffee, tea, or water.
What happens during the procedure?
You will be given a sedative to help you relax. A local
anesthetic will be injected into your groin to help keep you
from feeling pain.
Your health care provider will put a needle into a groin
vein or artery, depending on which heart valve has the
problem, and guide a small catheter into the blood vessel.
A catheter is a long tube used to inject fluid, introduce
other catheters and instruments, and measure blood pressure.
Your provider will guide a wire within the small catheter
into your heart and through the problem valve. Then the
first catheter will be removed and a larger balloon
catheter will be guided through the blood vessel over the
wire. Your health care provider will inject a contrast dye
into the balloon so that it shows up with x-rays. Using
these x-ray images, your health care provider will check if
the balloon is in the right place. Inflating the balloon
makes the valve opening larger.
When the balloon is inflated, you may feel some temporary
pain. This is not uncommon, but you should tell your health
care provider. This process may be repeated several times
until the valve opening is the right size. Then your
provider may replace the large catheter with the smaller one
and inject dye through the catheter. The smaller catheter
may be used to measure the pressure in your blood vessels
again and take another x-ray.
The catheter and the wire will be removed and pressure
applied over your groin to control any bleeding.
What happens after the procedure?
You will be taken to a bed in the coronary care unit or the
intensive care unit, where you will be carefully watched
overnight. Your heart will be monitored for at least 24
hours. Your blood pressure and groin sites will be checked
often for several hours.
While recovering from the procedure, don't bend your legs
where the catheters were inserted and don't sit upright in
bed or try to get out of bed. If you need to move, ask a
health care provider to help you. Being careful with your
movements will help prevent bleeding from the catheter
sites.
The next morning the IV drips (lines into the vein) may be
stopped. After the lab checks how well your blood is
clotting, the catheter may be removed. After the catheter
is removed, your health care provider will put firm pressure
on the site for about 20 minutes.
Your health care provider will
help you walk around the room. Sometime after this, you
will be transferred from the coronary care unit or intensive
care unit to a regular room. You will be encouraged to walk
around the room to prepare for discharge. The entire stay
in the hospital may last 1 to 3 days, based on your
condition.
Ask your health care provider what other guidelines you
should follow and when you should come back for a checkup.
What are the benefits of this procedure?
Your heart may work normally again. You may avoid having
open-chest surgery.
What are the risks associated with this procedure?
- A local anesthetic may not numb the area quite enough and
you may feel some minor discomfort. Also, in rare cases,
you may have an allergic reaction to the drug used in
this type of anesthesia. Local anesthesia is considered
safer than general anesthesia.
- There is a risk of infection or bleeding from this
procedure.
- Your heart may beat in an unusual way. You may need
medicine, electrical cardioversion, or a temporary
pacemaker.
- You may have an allergic reaction to the dye. You could
become nauseated or flushed. If your kidneys are not
working well, the dye may make them worse.
- Blood may form a clot around the catheter. The clot
could block the artery through which your health care
provider is inserting the catheter. You may need surgery
to reopen the artery.
- You may form a clot where the catheter was inserted and
lose the pulse in your groin. This may pose a threat to
the circulation in your leg. You may be given
medicine to dissolve the clot or, rarely, surgery may be
needed to remove the clot.
- The valve may tear when the balloon is inflated. This
may require valve-replacement surgery. The catheter may
puncture a vein or artery, or the heart itself, and cause
internal bleeding. Such a problem may require surgical
repair.
- When the catheter is inserted, debris on the wall
of the artery may become dislodged and pass down your
artery, causing a stroke or other blockage. You may
need surgery if this happens.
- There could be some bruising or bleeding at the site
where the catheter was inserted.
- During the procedure, your blood pressure could drop,
causing dizziness or heart rhythm disturbances.
- There is a chance the procedure might not work.
There is risk with every treatment or procedure. Talk to
your provider for complete information about how the risks
apply to you.
When should I call my health care provider?
Call your health care provider immediately if:
- You develop a fever.
- You become short of breath.
- You have a lot of pain.
Call your health care provider during office hours if:
- You have questions about the procedure or its result.
- You want to make another appointment.
